Caps, nozzle, & straw are all BpA and BPS free and are composed from polypropylene materials

2 Piece Silicon Jacket for Protective Covering, Easily removeable for Cleaning as well

BpA Free Patented Flip N' Sip Cap (Now With No-Tilt Drinking Straw) The patented Flipí N Sip cap has the remarkable ability to provide a good flow of water free of air bubbles and noise. This is possible because of the small clear Silicone air bladder located just beneath the flip up drinking spout

Because the air bladder is tiny and made of clear silicone, consumers sometimes lose it which necessitates the purchase of another entire cap, please keep an eye on this. If it falls out due to direct pressure it can be reseated

While the bottle and cap are dishwasher safe, please wash the cap on the top shelf only or by hand, with the drinking spout closed

Protective Cap can also be used as attachment

Unique Countour Design for Easy Grip

Great alternative to plastic and metal bottles and are ideal for storing liquids of most any kind
